The roasted #coffee placed in the upper chamber. The #beans are ground at the time of use or as close as possible to the time of use, thus preserving the aroma, freshness and taste of the coffee and serving it.

Coffee grinders are divided into automatic, semi-automatic and manual. If we examine them one by one;

Automatic Coffee Grinder;

If the daily coffee consumption of a cafe is below two kilograms, an automatic coffee grinder is very important in terms of usage and providing quality coffee. The digital screen of automatic coffee grinders is also a setting panel where coffee grinder settings can be easily adjusted. When the correct weight of coffee is determined according to the recipe of the product to be prepared, it can be consumed quickly and in accordance with the recipe every time. In addition, many automatic coffee machines also have a coffee counter on their digital screen. Thanks to this counter, it is easy to keep track of how many coffees have been sold. One of the main features that distinguish automatic coffee grinders from each other, apart from their external design, is the quality of the blades. Blade quality is one of the main features that determine the prices of all coffee grinders. Cafes that want to offer quality coffee and sell more than two kilograms per day prefer to serve the quality coffee they want to their customers with two automatic coffee grinders.

Semi-Automatic Coffee Grinder;

Since the semi-automatic coffee grinder is not a very popular grinder, its sales are almost non-existent. It has the same design as the manual mill. The main feature that distinguishes it from a manual mill is that it automatically starts grinding when the grinding chamber of the manual mill is empty.

Manual Coffee Grinder;

Cafes with a daily coffee consumption of over two kilograms use a manual coffee grinder for speed. Coffee is ground from the bean chamber at the top of the manual coffee grinder and accumulates in the grinding chamber at the front. Under the grinding chamber, there are separate compartments containing the manually adjusted recipe weight. Each of the hoppers can be adjusted to the same weight. It is not possible to set different coffee weights. When the slide bar located next to the grammage chamber is pushed, the coffee in the set grammage is instantly poured into the portafilter. Compared to the automatic coffee grinder, functional speed is gained more in this area.

Automatic Coffee Grinder? Or Should You Buy a Manual Coffee Grinder?

Although there is no clear answer to this question, both coffee grinders have different features depending on themselves and the amount of use.

Automatic coffee grinder is suitable for more accurate use and taste in terms of freshness and weight. Although there are generally no problems with single shots when adjusted correctly in a manual coffee grinder, adjusting the grammage correctly in double shots can be a disadvantage, contrary to the speed it provides. For example; A barista who uses 7 to 9 grams of coffee in a single shot espresso must add extra ground coffee to achieve the use of 16 to 18 grams of coffee in a double shot. In addition, while the daily amount of coffee used can be easily seen on the digital counter in an automatic coffee machine, it may be necessary to weigh the amount of beans placed in the upper chamber in a manual coffee machine beforehand. While the time required to grind 7 grams of coffee in an automatic coffee grinder is at least 3 seconds, it is 1 second in a manual grinder.
